Pretty much known around here if there are no front porch lights on there is no knocking on the doors. Then again back when I was a juvenile delinquent the people who turned off their front porch lights were the 1st targets about 1 am. I honestly can't say I ever TP'd a decent person's house though.
Seems every neighborhood has the same type house that gets TP'd each year. Wife wife spent about $5 on some candy and we honestly forgot it was Halloween night until my niece brought around our 2 year old grand niece for trick or tweeting.
We don't have side walks and these days people usually just drive their kids around to the houses of their relatives or close friends anyway. I would be real hesitant to take a young child out to a person's house that I did not really know pretty close to go trick or treating. It is a dying custom. Probably should be anyway. About like Valentines day, what a waste! That is a holiday made just for the candy and card makers if there ever was one.
Now when I was younger about, say 30 some odd years ago Halloween was a blast. We had a fun time around here. Not so anymore. See very few people out on the streets in NC these days. If my children were 10 I am not sure what I would do about it. Probably take them to my parents and sister's houses and that would be it.
